The ASTM D 1037 six-cycle accelerated-aging test for wood-based panel products was analyzed to determine how each successive aging cycle and selected steps in each cycle contribute to panel deterioration. Hardboard, particleboard, flakeboard, waferboard, and oriented strandboard were evaluated. The rate of panel deterioration generally decreased with each successive aging cycle. Four cycles of ...

The effect of pseudowollastonite (Pw) additions on the in vitro bioactivity and compressive strength of composites based on calcium aluminate cement (CAC) was studied. Composites were prepared by mixing calcium aluminate clinker with pseudowollastonite (5 and 10 wt%) at a w/c ratio of 0.4 (0.015M LiCl aqueous solution). In order to assess the in vitro bioactivity and compressive strength, compo...
